PGT-A embryo testing in Turkey: what it is and how it works
PGT-A embryo testing (preimplantation genetic testing for aneuploidy) checks whether an embryo made through IVF has the normal number of chromosomes, 46, before it is transferred to the womb. An embryo with too many or too few chromosomes, called aneuploid, is the most common reason an embryo fails to implant, ends in miscarriage or, more rarely, leads to a condition such as Down syndrome. Chromosome errors become more frequent as the egg's age rises, which is why PGT-A is most discussed for women in their late thirties and forties. The test is an add-on to an IVF or ICSI cycle: the embryos are created in the laboratory, a few cells are sampled from each, and only embryos reported as chromosomally normal are chosen for transfer.
This guide explains how the testing works, what the evidence actually shows, who may benefit, what it adds to the price and how to check a clinic. It sits within our wider guide to IVF treatments in Turkey.
How does PGT-A work, from biopsy to result?
After egg collection and fertilisation, the embryos are grown for five to six days to the blastocyst stage. An embryologist makes a tiny opening in the outer shell and removes about five to ten cells from the trophectoderm, the layer that will form the placenta, not the inner cell mass that becomes the baby. The sample is sent for next-generation sequencing (NGS), which counts the chromosomes in each sample. The embryo itself is frozen by vitrification while it waits.
Results take roughly one to two weeks, depending on whether the testing is done in the clinic's own laboratory or sent away. Embryos are reported as euploid (normal), aneuploid (abnormal) or mosaic, meaning a mixture of normal and abnormal cells. A euploid embryo is then thawed and transferred in a later cycle, which is why PGT-A almost always involves a freeze-all approach and a frozen embryo transfer.
Does PGT-A actually improve the chance of a baby? What the evidence says
This is the most debated question in fertility medicine, and an honest answer is nuanced. Euploid embryos do implant more often per transfer than untested ones, and transferring only euploid embryos can shorten the time to pregnancy and reduce miscarriage in some groups. However, randomised trials in unselected patients have not shown a clear increase in the cumulative live birth rate per egg collection, because an embryo labelled abnormal might have been able to produce a healthy baby, and some patients have no euploid embryo to transfer. The UK regulator, the Human Fertilisation and Embryology Authority (HFEA), gives PGT-A a red rating on its add-ons list, meaning there is no reliable evidence that it improves the chance of having a baby for most patients.
The test itself has limits: it samples a few cells that may not represent the whole embryo, mosaic results are hard to interpret and a false positive may lead to a good embryo being discarded. Most specialists suggest discussing PGT-A for specific reasons rather than as a routine step.
PGT-A embryo testing cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for the testing alone, per cycle, as an add-on to IVF. They exclude the IVF cycle, medication and embryo transfer, which are priced separately. The price depends on the number of embryos biopsied, the laboratory and the technology used. Each clinic confirms its own price in a written quote.
| Country | Approximate cost range (testing only) |
|---|---|
| Turkey | €600 – €2,500 |
| United Kingdom | €2,500 – €5,500 |
| United States | €3,000 – €8,000 |
| Germany | Rarely permitted; where offered about €3,000 – €6,000 |
What changes the price: usually a base fee for the biopsy and a charge per embryo tested, so the cost rises when you have many blastocysts; whether freezing and storage are included; and the fee for a later frozen transfer. Ask whether the quote is per embryo or per cycle, and what happens to the cost if no embryo reaches the blastocyst stage. Take care that the figure is also compared with your age-specific chance of success, not only with the price.
PGT-A, PGT-M or PGT-SR: which genetic test does your situation need?
The letters describe different questions. PGT-A screens for the number of chromosomes in embryos from patients without a known genetic disorder. PGT-M tests for a single inherited gene condition, such as cystic fibrosis, which is why it is used by known carriers; this older approach is covered in our guide to preimplantation genetic diagnosis. PGT-SR checks for structural rearrangements when a parent carries a balanced chromosome translocation.
| Test | What it looks for | Typical limits |
|---|---|---|
| PGT-A | Extra or missing chromosomes | Mosaic results are hard to interpret; no proven gain in live birth rates for all patients |
| PGT-M | One known inherited gene condition | Needs a prior family genetic work-up and a custom probe |
| PGT-SR | Chromosome rearrangements in a carrier parent | Rarely needed unless a translocation is known |
| No testing, morphology grading | Visual embryo quality | Cannot see chromosome errors |
Legal rules differ between countries. In Turkey embryo testing is regulated by the Ministry of Health and allowed for defined medical indications; selecting an embryo for non-medical reasons such as the sex of the baby is not permitted. Ask the clinic in writing whether your indication is covered.
Who may benefit from PGT-A, and who is unlikely to?
Reasons clinics typically suggest PGT-A include recurrent miscarriage, repeated implantation failure, an earlier pregnancy with a chromosome abnormality and, in some centres, advanced maternal age. Patients are more likely to value it if they produce several blastocysts, because the test needs more than one embryo to choose between.
You are less likely to gain if you are young with a good response and have not had repeated losses, because most of your embryos will be normal anyway, or if you make only one or two embryos, because a single embryo labelled abnormal leaves you with nothing to transfer. Patients who object to discarding embryos for personal or religious reasons should also consider this before testing. A clear conversation with your specialist about expected benefit is more useful than a standard offer.
How PGT-A fits into an IVF cycle: stimulation, biopsy and transfer step by step
PGT-A begins with an ordinary IVF cycle: ovarian stimulation, described in our guide to pharmacological stimulation for IVF, then egg collection under sedation, ICSI or conventional fertilisation and culture to day five or six. The biopsy and freezing take place in the laboratory without any additional procedure for you. After the results, a frozen embryo transfer is planned in a natural or medicated cycle, usually one to three months after egg collection. See embryo transfer for what that day involves.
The biopsy is done under a microscope by an embryologist and takes minutes per embryo. Experience matters, because poor technique can harm the embryo, and a laboratory that biopsies regularly will have its own survival and success data.
Timeline, recovery and how long to stay in Turkey
There is no recovery from the testing itself because it is done on the embryo, not on you. Recovery refers to the IVF steps around it: egg collection leaves most women with mild cramping and bloating for a day or two, and transfer needs no anaesthetic. Stimulation takes about 10 to 14 days, usually partly at home with monitoring scans, and egg collection is followed by the embryo culture period.
Because PGT-A means a frozen transfer, many patients make two trips: about 10 to 14 days for stimulation and egg collection, then 3 to 5 days later for the transfer once results are back. Some clinics can freeze the embryos, and arrange transfer at a local clinic at home if the Turkish team shares the records. Check the exact plan before you book flights.
PGT-A results: what does a normal, abnormal or mosaic report mean?
A euploid report means the sampled cells had 46 chromosomes, and it raises but does not guarantee the chance of implantation. An aneuploid report means an abnormality was found in the sample, and most clinics will not transfer that embryo. A mosaic embryo has a mix of normal and abnormal cells; some mosaic embryos have produced healthy babies, so clinics differ in whether and how they transfer them, usually after genetic counselling. Because the biopsy is a sample, a normal result is not a prenatal diagnosis, and doctors usually recommend standard screening in pregnancy. Ask the clinic how it classifies mosaic results and what its own transfer policy is, as this strongly affects how many embryos you can use.
Risks and limitations of PGT-A embryo testing
The main risks relate to the embryo rather than to you. A biopsy can in theory damage an embryo, although studies using modern methods show no clear harm when performed by experienced teams. Other limits include false positives and false negatives, mosaic results that are hard to judge, the possibility that no embryo is euploid, extra cost per embryo and the emotional strain of waiting for results. As with all IVF there are the risks of ovarian hyperstimulation, multiple pregnancy and miscarriage. The HFEA and professional bodies such as the European Society of Human Reproduction and Embryology advise that patients should be told clearly that PGT-A is not proven to raise live birth rates for everyone.
How to choose a clinic, red flags and questions to ask
Choose a licensed IVF centre with an on-site embryology laboratory, transparent success data by age and a genetic counsellor who explains results. Red flags include pressure to test every embryo regardless of your age and history, promises that testing "ensures" a healthy baby, vague pricing per embryo and no policy on mosaic embryos.

Frequently asked questions
PGT-A checks the number of chromosomes in a few cells taken from an IVF embryo before transfer. Embryos reported as chromosomally normal are chosen for transfer, because chromosome errors are a common reason for failed implantation and miscarriage.
Euploid embryos implant more often per transfer, but trials in unselected patients have not shown a clear rise in live birth per egg collection. The HFEA gives PGT-A a red rating, so discuss your own benefit.
Roughly €600 to €2,500 for the testing alone in Turkey, compared with about €2,500 to €5,500 in the UK. Prices are often per embryo, and the IVF cycle itself is priced separately.
A few cells are taken from the layer that becomes the placenta, not the baby. Studies show no clear harm when experienced embryologists perform it, though any procedure carries a small theoretical risk.
Usually one to two weeks. The embryos are frozen while waiting, and a euploid embryo is thawed and transferred in a later cycle, so the process takes longer than a fresh transfer.
Couples with recurrent miscarriage, repeated implantation failure, a past chromosome-related pregnancy or, in some centres, older maternal age. Young patients with good embryo numbers are less likely to gain.
It contains both normal and abnormal cells. Some mosaic embryos have led to healthy babies, so clinics differ on whether to transfer them, usually after genetic counselling.
No. PGT-A counts chromosomes in couples without a known genetic disorder, while PGD, now called PGT-M, looks for a specific inherited gene condition in known carriers.
Embryo testing is regulated by the Ministry of Health and used for defined medical indications; choosing an embryo for non-medical reasons such as sex is not allowed. Ask the clinic to confirm that your case is covered.
Stimulation and egg collection need about 10 to 14 days, and the frozen transfer after results needs a further 3 to 5 days. Some clinics arrange transfer at a clinic near you.
